Round Cairns 430m North West of Henrhyd is a prehistoric round cairn located in Wales and protected by Cadw as a scheduled monument. The monument sits upon bedrock of the South Wales Upper Coal Measures Formation, a sequence of mudstone, siltstone and sandstone interbedded with coal, ironstone and ferricrete layers deposited during the Westphalian period. This geology has shaped both the monument's construction materials and the landscape it occupies.
Round cairns of this type typically date to the Bronze Age and functioned as burial monuments, often marking the graves of significant individuals within prehistoric communities. The stone construction utilised local materials available from the surrounding Upper Coal Measures Formation, building a distinctive dome or conical mound visible across the landscape.
Today the cairn remains an important archaeological record of Bronze Age funerary practices and settlement patterns in this region of Wales. Its preservation as a scheduled monument ensures that this prehistoric burial site continues to contribute to understanding ancient communities and land use across the South Welsh valleys.
